Harbaugh fired his offensive coordinator in Week 15 of the NFL season. That qualifies as smacking the panic button harder than a helmet-to-helmet job by Ed Reed.

“We felt this would help us be the best we can be down the stretch,” Harbaugh said Wednesday. “That’s what we decided to do.”

Ravens quarterback Joe Flacco said “not much is going to change” with Jim Caldwell calling plays instead of Cameron. Flacco told local reporters he was stunned by the move.

None of us should be. It qualifies as the sort of unpredictable move we expect with a Harbaugh on the sideline. There’s a madness to their method.

Manning is 8-2 against the Ravens. The Broncos are 0-5 against the Ravens in Baltimore. One trend will change Sunday at M&amp;T Bank Stadium.

If not for the expected return of Ray Lewis, who, like Manning, raises all ships, the Broncos should be considered major favorites in Baltimore. Instead, the Broncos are considered 3-point favorites in Las Vegas.

Manning - the quarterback who wasn’t courted by San Francisco, according to San Francisco’s coach - is tight with Caldwell and Cameron.

“I really felt (Caldwell) took my game to another level. He’s also been a tremendous friend to me and mentor,” Manning said. “I miss being around him every day. I miss his friendship every day. That’s how I feel about Jim.”

We know the Harbaughs are winners. Jim’s 49ers are 9-3-1 and leading the NFC West. John’s Ravens are 9-4 and leading the AFC North.

I loved the San Francisco coach going with Kaepernick. The Niners aren’t winning the Tecmo Bowl, much less the Super Bowl, with Alex Smith.

I loved the Baltimore coach saying this Wednesday about the Broncos: “It’s probably going to be tough for us to hang in there.”

Actually, I love almost everything about the brothers’ daredevil coaching style.
